New massive Botnet twice the size of Storm

A new botnet twice the size of Storm has ballooned to an army of over 400,000 bots, including machines in the Fortune 500, according to botnet researchers at Damballa.

The so-called Kraken botnet has been spotted in at least 50 Fortune 500 companies and is undetectable in over 80 percent of machines running antivirus software. Kraken appears to be evading detection by a combination of clever obfuscation techniques, including regularly updating its binary code and structuring the code in such a way that hinders any static analysis, says Paul Royal, principal researcher at Damballa.
